OAKLAND — Like many other customers who stopped by the Eastmont post office to pick up or drop off mail Tuesday afternoon, Bill Bounthon had no idea that his almost daily routine for the past 16 years might change.

The Eastmont and Byron Mumford post office branches in Oakland are on the chopping block, and customers are not too happy about it.

“I had heard that mostly rural post offices might be shut down,” Bounthon said. “I had no idea this one might close.”

Yvonne Hodge also has a box at the Eastmont branch at 8022 MacArthur Blvd. She said she would probably switch to the Marcus Foster branch at 92nd Avenue and International Boulevard.

“It will be an inconvenience,” she said. “I’d rather they cut Saturday mail service than close this post office. I can get my bills on Monday; can’t do anything about them on Saturday anyway.”

The two Oakland post office branches are among 3,700 nationwide that the U.S. Postal Service announced it might close. The postal service has been closing branches since 2009 to save money and streamline services.

The Eastmont branch serves a large residential and commercial community in East Oakland. The Byron Mumford branch is downtown in the federal building at 13th and Clay streets.

There was no information on why these two post offices were chosen. More than half of the branches are located in rural areas, and 84 percent take in less than $27,500 in annual revenue, according to the U.S. Postal Service.

Those facts mean little to Annie Turner, who has disabilities and uses a wheelchair to get to the Eastmont post office to drop off and pick up her mail. Many of the personal mailboxes in the neighborhood get broken into, and people feel safer picking up their mail at the local post office.

“I don’t know what I’ll do,” she said. “A lot of people who live on this block are disabled. Where will we go for our mail?”

Derrell Davis has a box at the Eastmont branch although he no longer lives in the neighborhood. He said he hopes the decision to close the post office is not final. This is the third list of possible closures published by the postal service since 2009, and many of the branches on those lists are still open.

Otto Warmbier was arrested in January 2016 at the end of a brief tourist visit to North Korea. He had been medically evacuated and was being treated at the University of Cincinnati Medical Center when he died at age 22.
